This paper explores the removal of organics from soils in a simulated in-situ environment using aqueous solution extraction. A laboratory investigation is described in which organic compounds representative of the major groups of organic contaminants were adsorbed in low concentrations onto slightly organic, loamy soil, and various aqueous solutions were permeated through the soil under controlled hydraulic gradients and effective stress conditions, simulating the in-situ extraction process. The effectiveness of the extraction process was evaluated by periodically measuring the concentration of the contaminants in the permeameter effluent. Simple contact shaking tests were also performed and compared with the results of the permeation tests to ascertain whether contact shaking tests can be used as an index to the effectiveness of permeation testing. The results may be applicable to injection and extraction wells, in which the solution extract is pumped to a location on the ground surface for treatment.
